In his map, "The pleasant places to live," Norton plotted a list of the top five U.S. cities with the most pleasant weather, which he defined thusly, according to the Cities blog:

Being from Atlanta, the engineer defined pleasant using rather Southern parameters: The mean temperature must be between 75 and 55 degrees, and the day's minimum can't drop below 45 nor the max exceed 85. Using that criteria and a mother lode of meteorological data from NOAA, he was able to elicit what are allegedly the country's most fair-weather burgs. Not surprisingly, they are all in California.

Norton also calculated the average number of pleasant days for five other cities that he said had the least pleasant weather, based on an analysis of 23 years of NOAA data. They are Mc Allister, Mont. (14 days); Northeast of Reno, Nev. (15 days); Clancy, Mont. (15 days); Douglas, Wyo. (15 days); and East of Cedarville, Calif. (16 days).

It has been a winter of dreadful weather so far. I spent January flying back and forth from New York expecting to find a different set of conditions at the end of each leg. Whichever way I went, bitter cold greeted me at the end of the jet way and often with a coating of slick ice. It’s hard not to dwell on anomalous and unpleasant weather. It got me wondering, though, where in the U.S. do you go if you want the most “pleasant” days in a year?

Norton's interactive map allows users to input zip codes to figure out the number of "pleasant" days in their respective cities.
